Prerequisites: Concatenate the CAbundle and the certificate file which we sent you using the following command.

> cat domain_com.crt domain_com.ca-bundle > ssl-bundle.crt

If you are Using GUI Text Editor (Ex: Notepad):

(i) To concatenate the certificate files into single bundle file, first open domainname.crt and domainname.ca-bundle files using any text editor.

(ii) Now copy all the content of domainname.crt and paste it on the top of domainname.ca-bundle file.

(iii) Now save the file name as ‘ssl-bundle.crt’.

Note: If you have not the received the 'ca-bundle' file in the ZIP that we sent you, you can download it from this article's attachments. (End of this page)

For our CCM "Comodo Certificate Manager" customers: since you receive multiple downloadable links you must make sure that you download the x.509 base64 encoded "Certificate Only" as well as the Root/Intermediate "Certificate only" files. You will be presented with .cer formatted files which you can change the file extension to .crt to complete the process above.

Installation:

1. Store the bundle in the appropriate nginx ssl folder

EX :

> mkdir -p /etc/nginx/ssl/example_com/

> mv ssl-bundle.crt /etc/nginx/ssl/example_com/

2. Store your private key in the appropriate nginx ssl folder,

EX:

> mv example_com.key /etc/nginx/ssl/example_com/

3. Make sure your nginx config points to the right cert file and to the private key you generated earlier:

Note: If you are using a multi-domain or wildcard certificate, it is necessary to modify the configuration files for each domain/subdomain included in the certificate. You would need to specify the domain/subdomain you need to secure and refer to the same certificate files in the VirtualHost record the way described above.

4.OCSP Stapling Support:

Although optional, it is highly recommended to enable OCSP Stapling which will improve the SSL handshake speed of your website. NginX has OCSP Stapling functionality enabled since version 1.3.7.

In order to use OCSP Stapling in NginX, you must set the following in your configuration:
